I support this, but would extend it to include the interactions of
aquatic plants with microbes (including epiphytic plants, eg diatoms)
in the surrounding water column. Many algae require, absolutely,
compounds produced by other micro-organisms (apart from CO2, obvious
nutrients, etc); few of these compounds have been identified
(vitamins, esp. B vitamins). Deleterious interactions have also been
detected....
